You need to click "highlight all" to highlight all occurrences. It's the checkbox to the right of the search box. If you enable it for the first time, you may need to hit enter in the search bar again for it to show up (it remembers the setting and works instantly the next search)

Apparently I'm just a moron and have never seen it has settings in 10+ years. Thanks!
